1.) In creating confidence intervals with 95% confidence, about 5% of the possible intervals will miss the true value of the population parameter. Why do some of the intervals miss the true parameter?

Select one:
A. Because the parent population is skewed and about 5% of the distribution is in the tail of the distribution.
B. Because the standard deviation of the sample is about 5% smaller than the population standard deviation.
C.Because some samples are taken in an incorrect way and we know from experience that this happens about 5% of the time.
D.Because about 5% of possible samples lead to a statistic in the extreme tails of the sampling distribution.
